Essential tremor (ET) is a movement disorder primarily characterized by upper limb postural and kinetic tremor. Although still under‐investigated, bradykinesia may be part of the phenotypic spectrum of ET. The aim was to evaluate bradykinesia features in ET through clinical examination and kinematic analysis of repetitive finger movements. Data collected in ET patients were compared with those recorded in Parkinson’s disease patients and healthy controls.

是否存在原发性震颤运动迟缓的证据？

原发性震颤（ET）是一种运动障碍，主要特征为上肢姿势性和动态性震颤。尽管仍未进行充分研究，但运动迟缓可能是ET表型谱的一部分。目的是通过临床检查和重复手指运动的运动学分析来评估ET中的运动迟缓特征。将在ET患者中收集的数据与在帕金森氏病患者和健康对照中记录的数据进行比较。
